What to do after a guy starts acting distant?

Long story short: he pulled away after we slept together because he was under the impression that I wanted something serious. This was a huge misunderstanding because I was enjoying just taking things slow and getting to know each other before jumping into a relationship.

He got scared off which left me really confused but he apologized for his behaviour. Now he wants to know what the next step is and I'm not even sure. Should I continue to see him?
